Nov. 28 1933. A. BIENENSTEIN TWISTING FILLER FOUNTAIN PEN Filed May 22, 1935 Cal UNITEDTSTATESV Patented Nov. 28, 1 933 1- v TWISTING FILLER FOUNTAIN PEN f Andreas Bienenstein, Toledo; Ohio, assignor' to The Conklin Pen Company, Toledo, 0l1io,a corporation of Ohio Application May 22, 1933., Serial Pi f-672,251
7 Claims. (01. 120-46) This invention relates to fountain pens, and
has primarily for its object to improve on those of the twisting filler type.
The invention is fully described in the following specification, and one embodiment thereof illustrated in the accompanying drawing, in which- Figure 1 is an enlarged elevation of a fountain pen partially in central longitudinal section with the filler parts in normal position. Fig. 2 is asimilar View with the filler control in the act of being screwed into position in the pen barrel and with the engaging end of the twisting filler held out of engaging relation to the control stem during such action. Fig. 3 is a central longitudinal section of the barrel and filler parts 'with portions in full, with the filler control in assembled position and showing the twisting filler member in the act of being engaged with the control stem by insertionof a rod through the filling end of the pen barrel, Fig. 4 is an enlarged cross-section taken on the line 44 in Fig. 1, and Fig- 5 is a modification of the tube and cup connection.
Referringto the drawing, 1 designates the pen barrel having the customary pen and feed-bar carrying nipple'2 at its forward or inlet end, and through which nipple ink may be introduced into the barrel, and having its rear end closed and provided with the twisting filler means embodying the invention, as hereinafter described.
The barrel 1 is preferably made in two sections comprising a forward section 1 and a rear section 1 which sections are of tubular form, and connected and hermetically sealed at-their inner ends by telescoping for a distance one on the other. In the present instance, the section 1 has'its wall, particularly at its rear end portion, thickened relative to the wall of the section 1", and'the outer surface of such thickenedportion annularly reduced for a distance from the inner end of the forward section to permit the inner end of the rear section to telescope thereover. At the same time the inner end of' the forward section provides a shoulder- 3 internally of the forward end portion of the section 1- for the purpose hereinafter described. The making of the barrel in two sections also has the added'advantage that the forward section may be composed of trans parent or translucent material, so that the'ink contained therein can be viewed through the wall of such sections and the rear section may be made from a material of an opaque nature, so that the filler parts enclosed therein may not be observed.
The filler means embodying the primary feature of the'present invention comprises a twister membef 4of tubular. form and composed of a v v suitable liquid proof pliant material, such, for.
closed by a nipple 5 and its rear end closed'by'a cup member 6. The nipple 5 has a reduced portion telescoped within the forwardend of the tube or filler'member 4 and .has its outer end annularly flanged to snugly fit the boreof the barrel 1, and'particularly in-the present instance the bore of the rear barrel section 1?, sothat the nipple and connected end portion of the filler tube are anchored to the barrel preferably by frictional coaction therewith. The shoulder 3 acts as a stop for'co-action with the nipple 5 when forced into the barrel, and thus facilitates a proper positioning of the forward end por-' tion of the filler tube in the barrel during assembling. I i i The cup member 6 at the rear end of the filler tube 4 is preferably formed ofv sheet metal with its side wall of cylindrical. formand radially flanged. at its outer edge to serve as a stop for coaction with the end of the tube 4 when the cup member is inserted therein-J This member serves as a'plug. for closing the rear end of' the filler tube 4 and has its cup or cavity, opening rearwardly ,to receive and have pressed or close frictional engagement with the cylindrical headed end '7 of a control stem 8. If' desired, the flanged end of the cup 6 may be turned back in parallel relation to the cup Wall and employed to clamp the tube-end to the cup, as shownin The control stem Sis threaded'through'an axial opening provided in a plug or closure-memberQ for the rear barrel end, such member in the present instance being threaded entirely through the plug and having a'stop shoulderfor coaction with the plug end to limit the extent of move- .ment therein.- 'A control knob 10 is fixed on'the outer end of the stem 8 without the plug 9 and is adapted to have stop coaction. with the plug end when the stem 8 is turned home. When the knob 10' is tu'med to the left, or in a'direction to move the stem outwardly, the engagement of the .stem head 7 with the; filler tube 4 causes a twisting of the tube to expel at least a portion of the air therefrom, the extentof twisting being end of the stem from frictionally engaging the cup member 6 and causing a turning and consequent twisting of the filler tube ei'therewith, the knob 10 and its stem are provided with an axial opening 11 to permit a piece-of wire 12 to be ."xinserted therethrough and to centrally engage the bottom of the cup member 6 and press it out of engagement with the stem'head '1 during the turning of the plug 9 into the barrel. 'This having been accomplished, the wire 12 is removed and a rod-likemember 13 then inserted into the barrel through the inlet end thereof and through thefiller tube nipple '5 with-its inner end bearing against the innerend of thecup member 6, so that upon an application of sufficient inward pressure on the rod 13, the cup member is forced over the stem. head 7.into fric-.- tional engagement therewith. To facilitate centering the wire 12 with the cup member 6, when 1 pressure is applied from'one to the other, the
bottom of the cup member is provided with a central wire receiving depression .14. 'This'tends to prevent the engaging end of the wire 12 from slipping to one side or the other of thecup center when pressure is applied, and a consequent tilting and locking of the cup member in a depressed position in the barrel.
It is apparent that I have provided a simple means for connecting the control stem and twisting filler member and for. facilitating an as-- sembling of the parts.
I wish it understood that my inventionis not limited to any specific arrangement or form of the parts, and that it is capable of numerous modifications and changes without departing from the spirit of the claims.
Having thus described my'invention; what I claim as new, and desire to secure by" United States Letters Patent, is:
